       "The bulk is in-kernel pointer authentication, activity monitors and
        lots of asm symbol annotations. I also queued the sys_mremap() patch
        commenting the asymmetry in the address untagging.
      
        Summary:
      
         - In-kernel Pointer Authentication support (previously only offered
           to user space).
      
         - ARM Activity Monitors (AMU) extension support allowing better CPU
           utilisation numbers for the scheduler (frequency invariance).
      
         - Memory hot-remove support for arm64.
      
         - Lots of asm annotations (SYM_*) in preparation for the in-kernel
           Branch Target Identification (BTI) support.
      
         - arm64 perf updates: ARMv8.5-PMU 64-bit counters, refactoring the
           PMU init callbacks, support for new DT compatibles.
      
         - IPv6 header checksum optimisation.
      
         - Fixes: SDEI (software delegated exception interface) double-lock on
           hibernate with shared events.
      
         - Minor clean-ups and refactoring: cpu_ops accessor,
           cpu_do_switch_mm() converted to C, cpufeature finalisation helper.
      
         - sys_mremap() comment explaining the asymmetric address untagging
           behaviour"

      Pull x86 timer updates from Thomas Gleixner:
       "A series of commits to make the MSR derived CPU and TSC frequency more
        accurate.
      
        It turned out that the frequency tables which have been taken from the
        SDM are inaccurate because the SDM provides truncated and rounded
        values, e.g. 83.3Mhz (83.3333...) or 116.7Mhz (116.6666...).
      
        This causes time drift in the range of ~1 second per hour (20-30
        seconds per day). On some of these SoCs it's not possible to
        recalibrate the TSC because there is no reference (PIT, HPET)
        available.
      
        With some reverse engineering it was established that the possible
        frequencies are derived from the base clock with fixed multiplier /
        divider pairs.
      
        For the CPU models which have a known crystal frequency the kernel now
        uses multiplier / divider pairs which bring the frequencies closer to
        reality and fix the observed time drift issues"

      Pull x86 splitlock updates from Thomas Gleixner:
       "Support for 'split lock' detection:
      
        Atomic operations (lock prefixed instructions) which span two cache
        lines have to acquire the global bus lock. This is at least 1k cycles
        slower than an atomic operation within a cache line and disrupts
        performance on other cores. Aside of performance disruption this is a
        unpriviledged form of DoS.
      
        Some newer CPUs have the capability to raise an #AC trap when such an
        operation is attempted. The detection is by default enabled in warning
        mode which will warn once when a user space application is caught. A
        command line option allows to disable the detection or to select fatal
        mode which will terminate offending applications with SIGBUS"

      Pull timekeeping and timer updates from Thomas Gleixner:
       "Core:
      
         - Consolidation of the vDSO build infrastructure to address the
           difficulties of cross-builds for ARM64 compat vDSO libraries by
           restricting the exposure of header content to the vDSO build.
      
           This is achieved by splitting out header content into separate
           headers. which contain only the minimaly required information which
           is necessary to build the vDSO. These new headers are included from
           the kernel headers and the vDSO specific files.
      
         - Enhancements to the generic vDSO library allowing more fine grained
           control over the compiled in code, further reducing architecture
           specific storage and preparing for adopting the generic library by
           PPC.
      
         - Cleanup and consolidation of the exit related code in posix CPU
           timers.
      
         - Small cleanups and enhancements here and there
      
        Drivers:
      
         - The obligatory new drivers: Ingenic JZ47xx and X1000 TCU support

      Pull irq updates from Thomas Gleixner:
       "Updates for the interrupt subsystem:
      
        Treewide:
      
          - Cleanup of setup_irq() which is not longer required because the
            memory allocator is available early.
      
            Most cleanup changes come through the various maintainer trees, so
            the final removal of setup_irq() is postponed towards the end of
            the merge window.
      
        Core:
      
          - Protection against unsafe invocation of interrupt handlers and
            unsafe interrupt injection including a fixup of the offending
            PCI/AER error injection mechanism.
      
            Invoking interrupt handlers from arbitrary contexts, i.e. outside
            of an actual interrupt, can cause inconsistent state on the
            fragile x86 interrupt affinity changing hardware trainwreck.
      
        Drivers:
      
          - Second wave of support for the new ARM GICv4.1
      
          - Multi-instance support for Xilinx and PLIC interrupt controllers
      
          - CPU-Hotplug support for PLIC
      
          - The obligatory new driver for X1000 TCU

      staging/octeon: fix up merge error · 673b41e0
      Randy Dunlap authored
      There's a semantic conflict in the Octeon staging network driver, which
      used the skb_reset_tc() function to reset skb state when re-using an
      skb.  But that inline helper function was removed in mainline by commit
      2c64605b ("net: Fix CONFIG_NET_CLS_ACT=n and
      CONFIG_NFT_FWD_NETDEV={y, m} build").
      
      Fix it by using skb_reset_redirect() instead.  Also move it out of the
      
      This code path only ends up triggering if REUSE_SKBUFFS_WITHOUT_FREE is
      enabled, which in turn only happens if you don't have CONFIG_NETFILTER
      configured.  Which was how this wasn't caught by the usual allmodconfig
      builds.

      Pull scheduler updates from Ingo Molnar:
       "The main changes in this cycle are:
      
         - Various NUMA scheduling updates: harmonize the load-balancer and
           NUMA placement logic to not work against each other. The intended
           result is better locality, better utilization and fewer migrations.
      
         - Introduce Thermal Pressure tracking and optimizations, to improve
           task placement on thermally overloaded systems.
      
         - Implement frequency invariant scheduler accounting on (some) x86
           CPUs. This is done by observing and sampling the 'recent' CPU
           frequency average at ~tick boundaries. The CPU provides this data
           via the APERF/MPERF MSRs. This hopefully makes our capacity
           estimates more precise and keeps tasks on the same CPU better even
           if it might seem overloaded at a lower momentary frequency. (As
           usual, turbo mode is a complication that we resolve by observing
           the maximum frequency and renormalizing to it.)
      
         - Add asymmetric CPU capacity wakeup scan to improve capacity
           utilization on asymmetric topologies. (big.LITTLE systems)
      
         - PSI fixes and optimizations.
      
         - RT scheduling capacity awareness fixes & improvements.
      
         - Optimize the CONFIG_RT_GROUP_SCHED constraints code.

      Pull EFI updates from Ingo Molnar:
       "The EFI changes in this cycle are much larger than usual, for two
        (positive) reasons:
      
         - The GRUB project is showing signs of life again, resulting in the
           introduction of the generic Linux/UEFI boot protocol, instead of
           x86 specific hacks which are increasingly difficult to maintain.
           There's hope that all future extensions will now go through that
           boot protocol.
      
         - Preparatory work for RISC-V EFI support.
      
        The main changes are:
      
         - Boot time GDT handling changes
      
         - Simplify handling of EFI properties table on arm64
      
         - Generic EFI stub cleanups, to improve command line handling, file
           I/O, memory allocation, etc.
      
         - Introduce a generic initrd loading method based on calling back
           into the firmware, instead of relying on the x86 EFI handover
           protocol or device tree.
      
         - Introduce a mixed mode boot method that does not rely on the x86
           EFI handover protocol either, and could potentially be adopted by
           other architectures (if another one ever surfaces where one
           execution mode is a superset of another)
      
         - Clean up the contents of 'struct efi', and move out everything that
           doesn't need to be stored there.
      
         - Incorporate support for UEFI spec v2.8A changes that permit
           firmware implementations to return EFI_UNSUPPORTED from UEFI
           runtime services at OS runtime, and expose a mask of which ones are
           supported or unsupported via a configuration table.
      
         - Partial fix for the lack of by-VA cache maintenance in the
           decompressor on 32-bit ARM.
      
         - Changes to load device firmware from EFI boot service memory
           regions
      
         - Various documentation updates and minor code cleanups and fixes"

      Pull objtool updates from Ingo Molnar:
       "The biggest changes in this cycle were the vmlinux.o optimizations by
         Peter Zijlstra, which are preparatory and optimization work to run
         objtool against the much richer vmlinux.o object file, to perform
         new, whole-program section based logic. That work exposed a handful
         of problems with the existing code, which fixes and optimizations are
         merged here. The complete 'vmlinux.o and noinstr' work is still work
         in progress, targeted for v5.8.
      
        There's also assorted fixes and enhancements from Josh Poimboeuf.
      
        In particular I'd like to draw attention to commit 644592d3,
        which turns fatal objtool errors into failed kernel builds. This
        behavior is IMO now justified on multiple grounds (it's easy currently
        to not notice an essentially corrupted kernel build), and the commit
        has been in -next testing for several weeks, but there could still be
        build failures with old or weird toolchains. Should that be widespread
        or high profile enough then I'd suggest a quick revert, to not hold up
        the merge window"

       "These clean up and rework the PM QoS API, address a suspend-to-idle
        wakeup regression on some ACPI-based platforms, clean up and extend a
        few cpuidle drivers, update multiple cpufreq drivers and cpufreq
        documentation, and fix a number of issues in devfreq and several other
        things all over.
      
        Specifics:
      
         - Clean up and rework the PM QoS API to simplify the code and reduce
           the size of it (Rafael Wysocki).
      
         - Fix a suspend-to-idle wakeup regression on Dell XPS13 9370 and
           similar platforms where the USB plug/unplug events are handled by

           Ulf Hansson).
      
         - Extend the haltpoll cpuidle driver so that it can be forced to run
           on some systems where it refused to load (Maciej Szmigiero).
      
         - Convert several cpufreq documents to the .rst format and move the
           legacy driver documentation into one common file (Mauro Carvalho
           Chehab, Rafael Wysocki).
      
         - Update several cpufreq drivers:

              * Get rid of doc warnings and fix a typo (Christophe JAILLET).
      
         - Use built-in RCU list checking in some places in the PM core to
           avoid false-positive RCU usage warnings (Madhuparna Bhowmik).
      
         - Add explicit READ_ONCE()/WRITE_ONCE() annotations to low-level PM
           QoS routines (Qian Cai).

           a corner case (Neeraj Upadhyay).
      
         - Clean up the handling of hibernate compat ioctls and fix the
           related documentation (Eric Biggers).

           arrays instead of zero-length arrays (Gustavo Silva).
      
         - Fix list format in a PM QoS document (Randy Dunlap).

        the SPI tree.
      
        This has made a mess which I only just noticed while preparing this
        and I can't see a sensible way to unpick things due to other

        the exfat code (which is coming in again through the vfs tree in a

        But some code does come back, with the octeon drivers being found to
        actually be used in the wild, so those deletions are now reverted.

         - Cleanup fixed file update handling for stack fallback (Hillf)
      
         - Re-work of how pollable async IO is handled, we no longer require
           thread offload to handle that. Instead we rely using poll to drive
           this, with task_work execution.
      
         - In conjunction with the above, allow expendable buffer selection,
           so that poll+recv (for example) no longer has to be a split
           operation.
